Purchasing Managers' Index

The Purchasing Managers' Index is ISM's monthly diffusion index of manufacturing activity, released on the first business day with Services on the third and Hospital on the fifth.

It carries the industrial-demand and leading-indicator tags because factory activity drives demand for industrial space.

In this catalog it appears concretely: - ISM Report On Business — "monthly Manufacturing PMI and Services PMI with diffusion indices for new orders, production, employment, supplier deliveries, inventories and prices; tags: pmi, diffusion-index, industrial-demand, leading-indicator". - Port of Los Angeles cargo statistics — "leading-indicator".

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and ISM Report On Business lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open ISM Report On Business and confirm its record — "monthly Manufacturing PMI and Services PMI with diffusion indices for new orders, production, employment, supplier deliveries, inventories and prices; tags: pmi, diffusion-index, industrial-demand, leading-indicator" — against the files you actually receive.
2. Open Port of Los Angeles cargo statistics and confirm its record — "leading-indicator" — against the files you actually receive.
